For Tamron owners, do you find the little lag before VC kicks in makes you miss shots? I kind of liked both lenses but felt the tammy kind of jumped befor kicking in, not sure if a am explaining myself correctly.

Thanks again

Never used the VC version other than testing out in the local shop, but I would venture to bet you would miss many more shots with the slow AF of either the VC or non VC than if you had a Sigma 17-50 or Canon 17-55. Many more shots than waiting for VC to stabilize.
